Yes, AG Neovo's exclusive Anti-Burn-in™ technology prevents burnt-in "ghost" images. See this page for more information.

For AG Neovo displays with NeoV™ Optical Glass you can use commercially available computer screen cleaners or optical lens cleaners and buff with a soft cloth. A damp cloth with mild soap can also be effective, but avoid the use of abrasive cleaners. We also do not recommend frequent use of Ammonia based household cleaners as they may damage the optical coatings on the glass.
For AG Neovo displays without NeoV™ Optical Glass Technology, use only cleaning products specifically designed for LCDs and do not apply heavy pressure when cleaning the surface.

TN Panel technology is the most common on the LCD market, and benefits from high response times and can achieve 72% NTSC.
IPS Panel technology offers good response times and can achieve high colour accuracy and also offers wide viewing angles.
VA Panel technology tends to offer much higher contrast ratios and colour accuracy and is preferred for graphics applications.

AG Neovo displays work with any standard graphics card. Make sure that the graphics card supports the native resolution of the display.
For 2x2 4K video walls using a single video connection (supported by PN/PD-Series), we recommend using a Radeon™ RX Series graphics card or an NVIDIA Quadro® graphics card.

Please connect the PN or PD-Series displays with DisplayPort cables and change the DisplayPort version to 1.2 in the OSD menu of the displays. Use one of our recommended graphics cards to create the video wall in 4K 30 Hz.

By default, the video extenders mirror to multiple receivers but can be configured into a multipoint-to-multipoint configuration with multiple transmitters and many receivers. Multiple transmitters require a managed network switch with VLAN/IGMP support. Each VLAN acts as a separate HDMI over IP Channel on the network. When you use a single transmitter with many receivers, you should use IGMP to prevent other network devices from being flooded with multicast frames. Point-to-point is the most basic configuration of the video extender. To connect point-to-point, use an Ethernet cable to connect a transmitter directly to a receiver. You can use a switch that is not managed with a number of receivers, but you will only be able to mirror the HDMI input to the receivers.
